I've added more logging in this sort of situation, and made the TcpPort stuff
return a nil port rather than crashing - of course that probably just means
that something somewhere else will crash when it gets a nil port and it's
expecting a real one :-( However, I don't want to put much work into
TcpPort/NSConnection as I'm intending to replace it with the more MacOS-X
compatible GSTcpPort when/if I get time.
At least the changes should result in improved debug messages. when a machine
doesn't have its networking set up properly.
Q. Should we make NSHost throw an exception if it can't create a currentHost
object? at present, it simply returns nil.
